ABSTRACT:
The present invention is to provide an optical switch that enables size reduction of the switch, facilitation of positioning of an optical fiber, simplification of the structure of an actuator, improvements in assembly operability and reliability of the apparatus, facilitation of an application to a multi-core structure, facilitation of alignment of a plurality of optical fibers, and the like. A displacement stage 5 for mounting a single optical fiber 2 thereon, an elevating stage 20 for mounting a plurality of second optical fibers 3 thereon in a lateral line, and a linear encoder 14 for controlling a coil motor 9 are disposed in a case 1. The displacement stage 5 is displaced by the coil motor in the horizontally lateral direction. Simultaneously, the elevating stage 20 is moved upward by the actuator 19, and the first optical fiber 2 is caused to abut against an arbitrary second optical fiber to selectively couple them, thereby switching the optical path of an optical fiber.
